Getting this error while running ATF

[VENKATASAIA8700]

This step failed because the client error 'SPWidget:SCSS portalId is null (id: v84ec632c431e5210ca4c1f425db8f281 portalId: null): no thrown error' was detected on the page being tested. See failing Test Logs. To ignore these errors in the next test run, use 'Add all client errors to warning/ignored list' links.

The failure is due to missing portal context (portalId=null)

It’s not a crash, but your test flags it as an error

Fix it by:

Ensuring correct portal usage

Adding null checks in widget code

Running tests with proper session/context
